Specification of Letters Patent.
Patented Oct. 25,- 1910.
Application filed May 1910. Serial No. 560,124.
To all whom it may concern: L
Be it known that I, JOHN Lorros, citizen of the United States, residing at Albany, in the county of Albany and State of New ratus for Locomotives; and I do hereby declare the following to be a full, clear, and
exact description of the invention, such as will enable others skilled in the art to which 1t appertains to makeand use the same, refence marked thereon, which Form a part of this specification.
This invention relates to new and useful improvements in smoke consuming apparatus for locomotive fire boxes and the object in viewis to generally improve upon and render more eflicient the apparatus covered by Letters Patent No. 942,575 of December 7 1909 forarches for fire boxes of locomotivcs, the essence of the invention consisting of the introduction of heated air jetted into the fire box by steam and introduced as to commingle with the currents or drafts passing through the openings in the lire arch.
The invention consists further in the provision of means for automatically introducing heated air into the fire box commingled, with the smoke whenever the furnace doors are opened, the supply of air being cut off as the doors are closed.
The invention comprises further various details of '-.onstruction and combinations and arrangements of parts which will be hereinafter fl'lllydescribed and then specifically defined in the appended claims.
I illustrate .my invention in the accompanying lrawings, in which Figure 1 is a vertical' sectional view through a fire box and arch of a locomotive. Fig. 2 is a horizontal sectional View through the fire box above the arch. Fig. 3 is a front elevation of a portion of the furnace door and illustrating in section a steamactuated cylinder for automatically allowing steam to be injected into the .fire box above the grate as the furnace door is opened. Fig. 4 is a sectional View through the tire box above the arch showing a slight modification of my invention. Fig. 5 is a detail perspective view showing a modified form of the means for introducin the steam above the grate. Fig. 6 is a etail view,
artly in section, of aflexible nozzle. Fig. l is a detail sectional view on line 7--7 of Fig. 2, and Fi 8 is a detail sectional view on line 88 0 Fig. 4. f ""7 Reference now being had to the details of the drawings by letter, A designates the usual fire box of a locomotive and B the tines which. pass through the flue sheet B. C designates water tubes passing through the fire box at an inclination and upon which the fire brick D are mounted, which fire brick may be of any desired construe tion, preferably spaced apart as shown in order to break up the volume of heat as it passes from the tire box to the fines, it be-,
ing the purpose of the present invention to combine with this feature the introduction of steam to further the combustion of the carbon constituents of the smoke.
E designates a furnace door which, in the present instance, is shown as mounted to slide Vertically as is common on modern types of locomotives, said door movable in guideways E, and F designates a steam cyl- I iuder mounted at any suitable location, preferably near the door of the furnace, and F designates a pipe leading to and communicating with the contracted chamber F formed in the u )per end of the cylinder. It will be noted t at the top of said cylinder has an integral core F which is centrally apertured as at F and which core extends down within the cylinder at suitable distance in order to form said contracted portion of the cylinder. A piston G, provided with. suitable packing rings G, is mounted to reciprocate within said cylinder andv has a hollow central portion G adapted to receive said projecting core F a. suitable packing ring I-I being interposed between the circumference of the core and the adjacent wall .of the recessed or chambered portion of the piston. A pipe I communicates at one end with a port 1 leading'through'the up er portion of the cylinder and its lower end communicates with a valve casing I which communicates at one end with the lower portion of the cylinder beneath said piston and a needle valve J is mounted within said casing and adapted to re ulate the amount of steam to be introduce into the lower portion of the cylinder, a suitable hand wheel J being fastened to and adapted to control the needle valve. Communicatin witha port K in the circumferential 'wal of the cylinder is a pipe K which has a branching pipe K" leading therefrom, as shown in Fig. 20f the drawings, said'pipe connected to a 'pipe'K having a nozzle K with a washer K thereon, sa1d no zzle and washer being normally held in the positions shown in Figs. 2 and 6 of the drawings, by
1 a coiled sprmg K which is mounted upon the pin K and is interposed between a bracket plate K and an elbow K which connects the pipe K with the nozzle K.
It will be noted upon reference to, Fig. 6 of the drawings that the pipes K and K have flexible connection, as at K3 allowing the pipe K to tilt slightly as the force of the steam makes exit through the nozzle, thereby withdrawing the latter from the funnel-shaped entrance to the casing K. Each of said casings K one upon either side of theboiler, is provided with a laterally projectingport K which communicates with a duct L leading into a hollow triangular flue N, a cross sectional View of which is shown in Fig. 7 of the drawings; and which flue rests upon the upper faces of the brick forming the arch at the ends thereof. Said flue is provided with exit openings N positioned at intervals, preferably over and adjacent to the upper surface of each line of brick and intermediate the openings-between the rows of brick. Bolts L are passed through said casing K and the flue N, as shown in Fig. 2 of the drawings, and serve to hold the casings and flue securely in place.
Referring to Fig. 3 of the drawings will be seen an angle lever O pivotally mounted at 0' upon a pin adjacent to the sliding furnace door, and O designates a lug or pin projecting from the door and is designed to contact with said lever to tilt the latter as the door is raised and lowered. Pivotally connected to the lower end of said lever is a link Q which in turn is pivotally connected to a slidiii member Q, the upper surface of which is inclined as at Q and upon which inclined surface the lower end of the valve stem Q of the valve Q is adapted to ride, it being the ofiice of the member Q to open said valve as the link Q, is drawn toward the furnace door in the by the pipe It? may have a movement to-- ward or away from the boiler. Each of said pipes R is provided with a series of nozzles R having tapering portions R, each oposite each duct R which lead through the boiler and communicate with the interior of the fire box immediately above the brick forming the arch. Said pipe R there being one upon either side of the boiler similarly constructed, is provided with a steam cylinder R in which a piston S is mounted, the stem S of which piston is fastened to the outer face of the boiler. A spring S is fastened at one end to the pipe R? and its other end connected to the reservoir R, the otiice of which spring is to normally hold the nozzles R in contact with the ducts R to close the same.
Referring toFig. 5 of the drawings will be seen a still different modification of my invention and in which I have shown fines T resting upon the upper surface of the brick of the fire arch and the-ends thereof and each of said lines is provided with a nozzle ,1" opening between the openings in the arch and. corresponding ends of said fines and funnel-shaped as at T Said funnel-shaped ends are ada )ted to be positioned preferably at or near the front wall of the fire box, and T is a pipe adapted to have flexible connections at its lower end with a supply pipe leading from the boiler. A yoke T is adapted to be fixed to the wall of. the furnace and has a screw fixed thereto with an adjusting nut T upon the end thereof. A coiled spring T is mounted upon said screw and interposed between the pipe T and the yoke, the office of said spring being to normally hold the nozzles V, one mounted. at the end of each branching portion of the pipe T and centrally in alinement with the openings in the funnel ends of the pipes T, in closed relation and serving to normally close said openings.
The operation of my invention will be readily understood and is as follo\\'s:--lteferring to Fig. (3 of the drawings, steam is adapted to be supplied to the cylinder through the pipe 1 a constant jet of live steam being allowed to pass by the needle valve into the lower portion of the cylinder. As the lower portion of the cylinder has a its highest position and in which position exit of steam from the cylinder to the pipe K will not be permitted. When the furnace door is opened, the pin or lugO thereon coming in contact with the inclined edge of the lever 0 will cause the latter to tilt upon its pivot and the link Q connected to the lower end of said lever pulling upon the member Q upon whichthe val ve stem Q rides will cause the latter to be raised and the valve at the upper end thereof unseated, thus allowing the accumulation of steam within the lower portion of the cyl; inder to escape through the exhaust ports M to the atmosphere. As the steam exhausts from the lower portion of the cylinder, the
.live steam introduced through the pipe F direct from the boiler will cause the piston G to be forced down within the cylinder as the suppl of steam being fed through the pipe F wil overbala'nce the continuous jet of steam introduced through the needle .valve into the lower portion of the cylinder.
As the upper portion of the piston passes below the port K'leading to the exit pipe K, steam-Will escape from'the-upper por tion of the cylinder through the pipe K and-thence to and through the nozzles K,
the steam drawin in a et of air into the casings K whic air will pass thence through the ducts into the fluesnh which may be of any size or shape and which rest upon the upper surfaces of the arch. a r becomes ieated within said flues before it issues through the, openings N which are so positioned as to cause the air to come into intimate contact with the currents of heat and smoke passing up through the "openings, in the arch, thereby affording means whereby the carbon of the intense smoke may be more thoroughly consumed. As the Steam makes exit from the nozzles K, the pipes K will be caused to swing away from the casing K thus allowing air to be drawn by suction caused by the inrushing of the steam and fed into the tines within the fire box preparatory to its being heated andfcd therefrom into the fire box. This operation of introducing the air will continue whilethe furnace door is open. When the door is closed, the pin 0 coming in contact with the edge of the lower arm of the lever 0 will cause the latter tobe returned to its normal position, as shown in Fig. 3 of the drawings, and which move ment will move the member Q. from the boiler and the valve Q will seat. After the furnace door is closed, the steam will feontinue to be fed from the upper portion of the cylinder 'tothe fire box until the pressure below the piston in theacylinder over- The the feeding of the air may occur for a few seconds until the supply being fed through the needle valve returns the piston to its of steam and air will be cut off by the piston. As the air ceases to be fed into the fire box-above the arch, the coiled spring K will serve to throw the nozzles K into closed relation, as shown in Fig. (3 of the drawings, thereby preventing the ingress of outside atmospheric air into the fire box.
In the modified form shown in Fig. 4 of the drawings, a supply of steam is fed to the cylinder F as the door is opening and thence making exit through the pipes R will cause the latter to be thrown to the position shown in Fig. 4 of the drawings, the outer limit of the movement of the pipes R being limited bythe pistons S coming into contact with the inner ends of the cylinders R when the steam entering highest upper limit, after which the supply through the nozzles R will cause air to be injected into the fire box with the steam. When the supply of steam is cut off from the reservoir, the coiled springs S will serve to normally return thepipes R to their normal ing the ducts In the form shown in Fi 5 of the drawings, the princi le is identical to the other forms, the nozz es W being thrown back to allow steam and air to enter the fines and be introduced over'the arch in the fire box.
From the foregoing, it will be noted that, by the provision of an apparatus as shown and described, a simple and efiicient means is atforded whereby the smoke containing large quantities of carbon and unburned gases may be consumed by the introduction automaticall of steam and air at times when most needed orwhi'le the fire is being recharged.
